Rare genetic disorder gives clues to autism, epilepsy, mental retardation
A rare genetic disorder called tuberous sclerosis complex (TSC) is yielding insight into a possible cause of some neurodevelopmental disorders: structural abnormalities in neurons, or brain cells. view more (2008-09-24)
Mediator in communication between neurons and muscle cells found
A missing piece of the puzzle of how neurons and muscle cells establish lifelong communication has been found by researchers who suspect this piece may be mutated and/or attacked in muscular dystrophy. view more (2008-10-23)
Genetic tags reveal secrets of memories' staying power in mice
A better understanding of how memory works is emerging from a newfound ability to link a learning experience in a mouse to consequent changes in the inner workings of its neurons. view more (2008-02-22)
Neurons hard wired to tell left from right
It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour. For instance, in humans, the left half of the brain is concerned with language processing whereas the right side is better at comprehending musical melody. view more (2008-03-31)
Cancer-causing protein may heal damaged spinal cord and brain cells
Cancer researchers at Columbia University Medical Center have found that a protein known for driving the growth of cancer also plays a surprising role in restoring the ability of neurons to regenerate, making it an important target for addressing spinal cord damage or neurological diseases like Alzheimer's. view more (2006-06-29)
Researchers develop marker that identifies energy-producing centers in nerve cells
A protein that causes coral to glow is helping researchers at the University of Maryland School of Medicine to light up brain cells that are critical for the proper functioning of the central nervous system. view more (2007-02-02)
Most important actors in the growth process of neurons identified
Defects in the growth process of our neurons often underlie brain or nerve diseases, such as Alzheimer's disease or multiple sclerosis. view more (2006-10-12)
Columbia University researchers discover on-off switch for chronic pain
Chronic pain affects approximately 48 million people in the U.S. and current medications are either largely ineffective or have serious side effects. view more (2006-07-20)
Eating and body weight regulated by specific neurons
Researchers at Yale School of Medicine provide direct evidence that two parts of a neuronal system, one that promotes eating and another that suppresses eating, are critical for the acute regulation of eating and body weight. view more (2005-09-14)
Good news for the medical marijuana movement: pot proliferates brain cells and boosts mood
Most drugs of abuse decrease the generation of new neurons in the brain, but the effects of marijuana on this process, called neurogenesis, had not been clear. view more (2005-10-14)
Study suggests new treatments for Huntington's disease
Working with fruit flies, researchers have discovered a new mechanism by which the abnormal protein in Huntington's disease causes neurodegeneration. view more (2008-01-10)
Researchers identify a gene responsible for cases of Lou Gehrig's disease
A team of Canadian and French researchers has identified a novel gene responsible for a significant fraction of ALS (sporadic amyotrophic lateral sclerosis) cases. ALS is commonly referred to as Lou Gehrig's disease, an incurable neuromuscular disorder that affects motor neurons and leads to paralysis and death within one to five years. view more (2008-04-01)
Experts examine causes, treatment and prevention of glaucoma
Although scientists know progressive degeneration of retinal ganglion cells and their axons is the primary cause of glaucoma, researchers have yet to identify a way to stop or prevent the degeneration. view more (2009-03-05)
Protein shown to rally biological clock
A biologist at Washington University in St. Louis and his collaborators have identified the factor in mammalian brain cells that keeps cells in synchrony so that functions like the wake-sleep cycle, hormone secretion and loco motor behaviors are coordinated daily over a 24-hour period. view more (2006-11-30)
Scientists identify fundamental brain defect, probable drug target in fragile X syndrome
Scientists have discovered how the gene mutation responsible for fragile X syndrome--the most common inherited form of mental retardation--alters the way brain cells communicate. view more (2007-09-18)
UC Davis M.I.N.D. Institute researchers find fewer neurons in the amygdala of males with autism
Researchers at the University of California, Davis, M.I.N.D. Institute have discovered that the brains of males with autism have fewer neurons in the amygdala, a part of the brain involved in emotion and memory. view more (2006-07-19)
Researchers discover second depth-perception method in brain
It's common knowledge that humans and other animals are able to visually judge depth because we have two eyes and the brain compares the images from each. But we can also judge depth with only one eye, and scientists have been searching for how the brain accomplishes that feat. view more (2008-03-17)
Protein shown to play a key role in normal development of nervous system
A protein that enables nerve cells to communicate with each other plays a key role in controlling the developing nervous system. view more (2008-10-08)
Brandeis researchers propose model of neural circuit underlying working memory
Our ability to understand speech or decide which fruit in the store is freshest depends on the brain's dexterity in integrating information over time. view more (2005-12-21)
Discovery of post-stimulus activated release implies new mechanisms for dopamine release
The neurotransmitter dopamine continues to be released for nearly an hour after neurons are stimulated, suggesting the existence of secondary mechanisms that allow for sustained availability of dopamine in different regions of the brain including areas critical for memory consolidation, drug induced plasticity and maintaining active networks... view more...
